The Danish agricultural emissions are calculated and managed in a comprehensive
model complex called IDA (Integrated Database model for Agricultural
emissions), which is used to calculate both air pollutants compounds
and greenhouse gas related emissions. The livestock production has a great
influence on the Danish agricultural emissions. IDA works with approximately
38 different livestock categories, dependent on livestock category,
weight class and age. Each of these subcategories is subdivided according to
housing type and manure type, which results in about 200 different combinations
of subcategories and housing type and the emissions are calculated
from each of these combinations and aggregated to relevant main categories
in the reporting format.
Most of the emissions from agricultural activities are directly related to livestock
production. The remaining part comes from the use of synthetic fertiliser,
growing crops, NH3 treated straw, field burning of agricultural residues
and sewage sludge applied to fields as fertiliser. The number of animals can
be considered as the most important activity data in estimation of the agricultural
emissions.
The number of animals is mainly based on data from Statistics Denmark. For
data covering pigs, bulls and poultry, the number is based on slaughter data
also collected from the Agricultural Statistics. The production of sheep, goats
and horses typically take place on small farms below 5 hectare, which is not
included in the annual statistics and the production of these categories as
well as for deer and ostriches are therefore based on the Central Houseanimal
farm Register (CHR) managed by the Ministry of Food, Agriculture
and Fisheries.
Data concerning nitrogen excretion, distribution of housing types until 2004
and handling of manure is based on data and information from DCA-Danish
Centre for Food ans Agriculture at Aarhus University and the Danish Agricultural
Advisory Service. From 2005 annual statistics covering housing
types are available from the Danish Plant Directorate.
Data related to use of synthetic fertiliser, both the amount of fertiliser and the
nitrogen content is based on statistics published by the Danish Plant Directorate.
Please refer to Chapter 6 and Appendix 2C for further information on emission
inventories for agriculture.

The waste sector consists of the four main NFR categories 6A Solid waste
disposal on land, 6B Waste-Water handling, 6C Waste incineration and 6D
Other waste.
Solid waste disposal on land and waste-water handling are only relevant in
relation to the greenhouse gas emissions of CH4 and N2O. These categories
are therefore not included in this inventory of LRTAP.
Waste Incineration covers the cremation of human bodies and animal carcasses.
Both are calculated as en activity multiplied by an emission factor.
